Rasta resin-PPh3BnCl, a new heterogeneous polysty- rene-based phosphonium salt, has been synthesized and used to catalyze cyanosilylation reactions of aldehydes and ketones. It was found to be more efficient as a catalyst than a similar hetero- geneous phosphonium salt anchored onto a polystyrene based on the Merrifield resin architecture of 2% divinylbenzene cross- linking. In these reactions rasta
Rasta 树脂-PPh3BnCl 是一种新型多相聚苯乙烯基鏻盐,已被合成并用于催化醛和酮的氰基硅烷化反应。发现它作为催化剂比锚定在基于 2% 二乙烯基苯交联的 Merrifield 树脂结构的聚苯乙烯上的类似多相鏻盐更有效。在这些反应中,只需通过过滤即可将 rasta 树脂-PPh3BnCl 与所需的反应产物分离,并且可以重复使用多次,而不会显着降低催化活性。
